Self-adaptive electron beam welding anti-sputtering device

Abstract

The invention relates to the field of electron beam welding, in particular to a self-adaptive electron beam welding anti-sputtering device. A self-adaptive electron beam welding anti-sputtering device comprises an anti-sputtering baffle, a side plate, a supporting table, a clutch hub, a sun gear, a combination part and an abutting device. The sun gear is a sun gear of a planetary gear mechanism, a joint surface of a clutch hub and a joint surface of the sun gear form a joint part, and the sun gear forms a welding part of electron beam EB work welding, and is formed into a circular ring shape surrounding a rotating shaft X at a predetermined interval when viewed from the direction of the rotating shaft X. The electronic beam welding anti-sputtering device solves the problems that an existing electronic beam welding anti-sputtering device cannot completely prevent splashing generated in the welding process, so that a clutch hub and a sun gear still generate deviation in the welding process, and meanwhile sputtering still exists.

Description

technical field [0001] The invention relates to the field of electron beam welding, in particular to an adaptive electron beam welding anti-sputtering device. Background technique [0002] In the prior art, the electron beam is controlled by the magnetic field to move rapidly in different positions, rapidly impact the workpiece, form a molten pool, and realize the welding of the connection between the two workpieces. The magnetic field or the magnetic field interference of the workpiece will cause trajectory deflection and affect the welding effect. Therefore, during the electron beam welding process, vacuum conditions must be adopted. Therefore, manual participation cannot be allowed during the time when the workpiece is placed and waiting for processing and before the processing is completed; [0003] Vacuum electron beam welding uses fast moving electrons and uses kinetic energy to impact the workpiece to generate thermal energy, forming a molten pool to complete the weld...

Problems solved by technology

[0005] The existing invention prevents the deformation of the workpiece when it is displaced to the electron beam torch by abutting the abutting part against the slope of the boss part and the connecting part, and thereby prevents the spattering problem during welding. However, due to the abutment The joint parts of the components facing the clutch hub and the sun gear of different sizes need to be replaced with suitable abutting parts, which cannot realize automatic adaptation, and because only the inclined surface of the connecting part is abutted alone, it is impossible to completely offset the displacement generated during the displacement process. all stresses;

[0006] Due to the rigid structure of the abutment parts and the inability to move laterally, there is still a distance from the welding part, which cannot completely prevent the spatter generated during welding, resulting in the deviation of the clutch hub and the sun gear during welding. sputtering problem;

[0007] Therefore, the existing technology / design is flawed;
